In the course of a brainstorming session on #apache-modules (IRC) last night, it was suggested that some of my modules might be of interest for the Apache core distro (mod_diagnostics was specifically identified). I have compiled a list of four filter modules that are opensource and sufficiently general-purpose that they could be of interest. They are all open source, and can be licensed under the Apache license if you are interested in adopting them.
Specifically: 1. mod_diagnostics mod_diagnostics is a very simple module that can be inserted anywhere in the filter chain, and logs buckets and brigades passing through. Typical usage is to insert it immediately before and after a filter in development to help with debugging and testing. 2. mod_upload mod_upload is an input filter for "multipart/form-data". It decodes the upload, passing the contents of an uploaded file through, and exporting uploaded data other than the file itself as an apr_table_t of name/value. A second filter is available to capture the file itself as a tempfile; this serves for handlers that need synchronous upload by guaranteeing that all the form data has been captured before processing. 3. mod_xml_gnome_xslt This XSLT output filter is spinoff from mod_xml (and is in more widespread production use than other mod_xml components). It performs XSLT transformation, and offers several optimisations including supporting a cache of pre-compiled stylesheets, and accepting a document tree in-memory as an alternative to conventional filter input. 4. mod_proxy_html (NEW!) Apache as a reverse-proxy has hitherto been incomplete, as it falls down when HTML links in proxied pages fail outside the proxy. mod_proxy_html is an output filter to rewrite HTML links where necessary into the proxy's address space. Any interest? -- Nick Kew
